Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103742, here are decompositions:
- 19 + 103723 = 103742
- 43 + 103699 = 103742
- 61 + 103681 = 103742
- 73 + 103669 = 103742
- 151 + 103591 = 103742
- 181 + 103561 = 103742
- 193 + 103549 = 103742
- 271 + 103471 = 103742
Showing the first eight; more decompositions exist.
